refactor(consent-sdk): split ConsentManager + framework adapters under 500 LOC

Phase 4: extract config defaults, Google Consent Mode helper, and framework
adapter internals into sibling files so every source file is under the
hard cap. Public API surface preserved; all 135 tests green, tsup build +
tsc typecheck clean.

- core/ConsentManager 525 -> 467 LOC (extract config + google helpers)
- react/index 511 LOC -> 199 LOC barrel + components/hooks/context
- vue/index 511 LOC -> 32 LOC barrel + components/composables/context/plugin
- angular/index 509 LOC -> 45 LOC barrel + interface/service/module/templates
